APPARATUS FOR DEGREASING WOOL.

SPECIFICATION forming part of Letters ?atent No. 675AO8, dated June 4, 1901.

Application filed December 26, 1900. Serial do. 41,151. (No model!) To aZZ whom, it may concern:

Be it known that I, Gnonens PELTZER, a citizen of Belgium, residing at Rue David, Verviers, in the Kingdom of Belgium, have invented certain new and useful Improvements in Apparatus for Removing Fat from Raw "Wool, (for which application has been made for a patent in Great Britain, dated October 6, 1900, No. 17,7645, and in Belgium, dated October 22, 1900,) of which the following is a specification.

This invention relates to certain additions to and modifications of wool-washing apparatus of known kind, so as to render them available for removing fat from raw wool, as will be described with reference to the accompanying drawing, which is a longitudinal section of a wool-washing apparatus modified according to this invention.

The tank, which is of known kind, provided with agitators and propellers Z) of the ordinary or any desired construction, designed to agitate and propel the wool, is charged in any suitable manner with a quantity of carbon tetrachlorid a and above it a layer of water I), which has less specific gravity than the tetrachlorid. At one end-the right-hand end of the tank there is a feed-roller c, driven by any convenient motor and mostly inclosed within a casing cl, the front side of which dips into the liquid in the tank to form a seal. The blades of the roller 0 fit against a curved part of the casing cl, so as to prevent com munication with the atmosphere. A roller 6 advances along the bottom of the tank the wool fed in by the roller 0. The front part of the tank is hooded over by a casing f, the rear side of which dips into the liquid to form a seal. This casing might be extended back, as indicated by the dotted lines f, to join the casing d, in which water would not be required to prevent the tetrachlorid from evaporating. From the front part of the casing f, beyond the pair of delivery-rollers g h, a channel 7r, containing a long traveling apron Z, extends to a discharging-roller m, mounted in a washing-tank a, and over this roller is a shield 0, which dips into the liquid in the tank 7L. Steanrpipes t for heating are arranged within the channel, and between the coils of these pipes at intervals are located steam-jet pipes. A steam-pipe 19 has a nozzle discharging a jet of steam into the channel It, the jet being directed toward the casing f, and a water-pipe q terminates in a distributing-nozzle Within the casing. A pipe 7, provided with a cook or valve, serves for expelling air from the easingf before starting the operation of the apparatus. A pipe 8, provided with a cook or valve, serves to remove liquid from the upper layers of the carbon tetrachlorid ct.

The apparatus operates as follows: The casing f having been approximately cleared'of air by blowing in steam by the pipe 19, the pipe r is closed. Raw wool, being then fed by the roller 0, is advanced along the layer of carbon tetrachlorid a and agitated in the usual way and delivered on a traveling apron, which carries it to the delivery-rollers g h, which deliver it onto the apron Z, along which it is carried to the roller m, which discharges into the washing-tank it. During the passage of the wool along the layer of carbon tetrachlorid ct the fat which it contains is dissolved and remains in solution in the tetrachlorid. Most of the liquid accompanying the wool is squeezed out by the rollers 9 7t, and such tetrachlorid as remains in the wool as it passes along the channel is evaporated by the current of steam passing over the wool. The steam conveying this vapor on entering the casing over a shield u, placed above the roller g, is condensed by the water discharged from the pipe q, the water of condensation and the condensed tetrachlorid descending into the tank, from which, either continuously or from time to time, portions are taken by the pipe 8 from the upper layers of the tetrachlorid (which, containing most fat, are the lightest) to be subjected to distillation for separation of the tetrachlorid from the fat.

Having thus described the nature of this invention and the best means I know for carrying the same into practical effect, I claim In a wool-cleanin g apparatus, the combination of a tank having means for propelling the wool, feeding means at one end thereof, a casing over it forming a liquid seal, a second casing arranged to exclude air from the con- In testimony whereof I have hereunto set tents of the tank, a channel extending from my hand in presence of two subscribing witsaid casing, a Washing-tank at the end of said nesses. channel, a delivery-roller therein, and steam GEORGES PELTZER.
